 D/A Converter AK4493S

The Topping DX1 uses the newest sub-flagship AK4493S chips of AKM´s Velvet sound technology. AK4493s is an upgraded version of the previous AK4493.

Plug and Play – Turn your PC into a HiFi source

Topping DX1 has a wide range of compatibility: Windows 10, Windows 11, MAC, Linux, IOS, Android can be used plug and play. Only for Windows ASIO applications, you need to install the driver and set it up. The USB hardware is based on XMOS XU208 and Thesycon custom driver (applicable to Windows, other systems are free if driver), which is stable and reliable.

No adapter required

Like other USB devices, the Topping DX1 does mot require an additional adapter for power supply. Only one USB cable can complete the power supply and data transmission.

Discrete LNRD

How to solve the noise problem from USB power? The Topping DX1´s answer is the Discrete LNRD circuit (low noise reference driver). The discrete LNRD circuit filters out the noise and interference of USB 5V power and provides stable and clean power supply of ultra-low noise reference level for DX1. With this technology, the noise of DAC part is lower than 2.0µV, and the noise of the AMP part is lower than 1.0µV. Even highly sensitive IEMs will not bother by noise.

Powerful output in a small hummingbird size

In such a tiny size, Topping DX1 can provide a maximum output of 280mW x 2 whitout additional power supply

280mW x 2 @32Ohm

190mW x 2 @64Ohm

51mW x 2 @300Ohm

Two gain settings

Topping DX1 provides two different gain settings, which greatly expands the range of headphone adaption.
